ITEM# / SR / CR / PT / GLE / OBJ / EXP / DESCRIPTOR
13. / x / 2 / N2C / 1 / A / Apply properties of operations to integers. (DOK2)

Answer: Example: Distributive property: 8 ( 3 + 2 ) = 8 · 3 + 8 · 2

Associative property: (8 · 3 ) · 2 = 8 · ( 3 · 2)

Distributive property involves multiplication AND addition/subtraction. Associative property involves all multiplication or all addition.
